I think I see what you mean now, and I understand that that would be possible. Wouldn't you need some extra parameters if it were a binomial distribution though? For a uniform distribution every item is equiprobable (i.e. there's only one uniform distribution for a given N) but there are many binomial distributions possible for a given N. (Disclaimer, I know very little about statistics.) So the fact that you aren't given those parameters in the question means you can't make much of a prediction if it were binomial. Edit: I read that binomial distributions are parameterized on both the number of trials and the probability of the two outcomes, so that kind of demonstrates my point doesn't it? You're not given the probability of Red and Green for the binomial distribution, so you can't really answer the question that way. You could assume it's 50/50, but that's an assumption that isn't justified by the question.
